PUMP-OPERATING MECHANISM.

Specification of Letters Patent. Patented NOV. 16, 1915.

To all whom it may concern: I

Be it known that I, SYLVESTER'V. FER- GUSON, a citizen of the United States, residing at Polson, in the county of Flathead and State of Montana, have invented certain new and useful Improvements in Pump-Operating Mechanism, of which the following is a specification.

This invention relates to a pump operating mechanism and the principal'objectof the invention is to provide an apparatus of the character described which is so con- '1 structed that a pump of the reciprocating vide an apparatus which will be compara- 'tively simple in construction and which will operate very efliciently.

This invention is illustrated in the accompanying drawings, wherein Figure 1 is a front elevation of the improved pump voperating mechanism shown applied to a pump; Fig. 2 is a sectional View taken along the line 22 of Fig. 1; Fig. 3

. is a top plan View of the pump operating mechanism; Fig. 41 is a side elevation of the pump operating mechanism; Fig. 5 is a section taken along the line 5 5 of Fig. 3; Fig; 6 is a fragmentary view in elevation showing a modified form of the pump operating mechanism. v

The frame of this pump operating mechanism comprises the standards 10 which have their upper ends connected by the cross bar 11 and which are connected with the side supporting bars 12 and 13. The opposite ends of the side bars 12 and 13 are connected with the transversely extending supporting bar or plate 14 which carries a substantially V-shaped bracket 15. One end of the bracket 15 is secured to the plate 14: and the bracket then extends away from the plate for a short distance as shown in Fig. 3 and is carried upwardly in spaced relation to the plate with its opposite end forming a bearing for the driven shaft 16. This bracket also forms 'a'bearing, for the shaft 17 the opposite end of which is mounted in the bearing 18 carried by the plate 14:. Upon the shafts 16 and 18 there has been provided gears 19 and 20 one of' which is a great deal smaller than the other. If it is desired to operate this pump operating mechanism by means of a belt passing around the pulley wheel 21 the large gear l9 will be placed upon the shaft 16 and the small gear placed upon the shaft 17 but if it is desired to operate this mechanism by means of a' handle 22, the large gear will be placed upon the shaft .17 and the small gear upon the shaft 16. This second arrangement is shown in Fig. 6.

The driven shaft 16 extends through thebearing blocks 23 and 24: which are connected by the bar 25 and carries a worm 26 which meshes with the teeth of the gear or pinion 27 mounted upon the crank shaft 28. This crank shaft 28 carries a roller 29 which is mounted in the longitudinally extending slot 30 of the arm 31. In order to pivotally mount the arm 31 there is provided links or standards 32 which are mounted upon the bolt 33 passing through a selected opening in the bar 33 and have their upper ends connected by the bolt 34; which passes through a selected opening formed in the arm 31 as shown in Fig. 2. This arm 31 carries plates or brackets 35 which are pivotally connected with the pump shaft 36 by means of the pivot bolt or rivet 37. When this mechanism is in operation, the apparatusis assembled and mounted as shown in Fig. 1 with the supporting brackets 38 clamped to the upper end of the pump 39 bymeans of the bolts 40. The shaft 17 is then rotated either by means of the crank handle 22 or by means of a suitable belt passing around the pulley wheel 21.. Rotary motionis transmitted from the shaft 17 to the shaftc16 through the medium of the gears 19 and 20, thus causing the shaft 16 to rotate and transmit rotary motion to the crank shaft 28 through the medium of the worm 26. and gear 27. As the crank shaft 28 rotates, the arm 31 will oscillate vertically, thus reciprocating the pump rod 36 and causing the water to be pumped out of the well. This water can flow out through the spout 11 or the spout can be closed by means of the valve 12 and the water conveyed to a suitable receptacle by a conduit pipe connected with the pump at any convenient point. This mechanism is there fore so constructed that it may be easily
